i v I i To all whom it man concern:

Be it known t at I, SAMUEL CRUMP, a citizen of the United States, and a resident of Caldwell, in the county of Essex and State of New Jersey, have invented certain new-and useful Improvements in Printin Presses, of which the following is a speci cation.

The invention relates to improvements in printing presses, and consists in the novel features and structure hereinafter described and pnrticulnrl pointed out in the claims.

The object 0 this invention is toconstruct a press and suitable attachments thereto for enabling the effectual automatic clennin or washing of the ink distributing and orm rollers, as well as the form, but more especially the rollers, while the semen-re on the press and driven by the press d iving means.

Severalmachineshavehereto orebeen produccd for cleaning or washing printers rollers in the use of which the rollers are re moved fromthe press and delivered to the machine and subjected while rotating or while rotating and traveling longitudinally to the action of one or more scrapers and finally to one or more driers. These roller washing machines have not genernll if at all, proven acceptable to the trade ior severnl reasons, among which may he mentioned their expense, thespnce they occupy, the cure they require, their liability to injure the rollers, the time they consume in cleaning the rollers and the necessity they involve of removing the rollers from the press and curryiug them to the machines.

My invention is based on the principle of transferring the color or ink from one roller to another in series throu h the chain of rollers to a final roller,'pre erubly a composition inkdistributing roller in the train, from which it is removed by a scraper held a ainst the same and delivered into a suita le receptacle. The roller to which the scraper is applied by being constantl deprived of its ink will become the p nt'of delivery for the ink from all the other roll-- ers in the train and graduall and in an almost incredibly short time all the ink on the rollers will transfer to said final roller and be removed, all of the rollers on the press becoming thoroughly cleansed and also dried of the kerosene or other solvent which I will pour on the rollers during the cleans- 5 ing operation for softening the ink, 'When" the form rollers are left in contact with-the form during the cleansing operation, the lat ter then being a part of the train, will also become effectually cleaned, the ink there'- from transferring to the rollers which are constantly drawn from by the roller to which the scraper is applied.

In carrying out my invention, 1 thus preferably apply to the ink distributing roller, which in accordance with my invention will be of composition, a scraper which, in a, transfer process, removes all of the ink or color, as well as the solvent employed, from all the rollers and form of a press. Whether the scraper is applied to the ink-distribuain roller dr other roller in the train, it wil always be -applied to a com osition roller. The scraper will only be applied to the inkdistributing roller when said roller is of composition,-that is formed with a yielding 76 composition surfacing and inclosing an interior core which may appropriately be a cylinder or length of tubing, since the merit of my invention resides in the combination of the scraper with a composition roller, whereby very great advantages are attained.

The invention is represented in tho nocompanying drawings, in which:

Figure 1 is a central vertical longitudinal section through a commercial press embodying my invention; Fig. 2 is a detached longitudinal section through the receptacle carrying the sore er blade and into which the matter cleane from the rollers is gathere-d and Fig. 3 is an enlarged end View of said receptacle, the scraper blade being shown in its operative position by full lines and in an inoperative position by dotted lines. 1

In the drawings, 10 designates the usual form-cylinder, 11 the ink-font, 12 the main ink-distributing rol1er,13 a series of com* positionform-rollers, 14 iron distributer roller's in en egement each with a pair of 4 said form-r01 ers, 15 a series of composition rollers in enga ement with saidqnain ink-- distributing r0 ler, and '16- an oscillatory roller of usual character for transferrin the ink from the font 11 to one of said ro lots 15, while-17, 18 respectively denote rollers 106 for transferring the lnk from the distributor 12 and a pair of its cooperating rollers 15 i to one of the distributor rollers 14 for the form-rollers 13. v

The main distributor roller 12 is a com- 110 roller and has pivotall mounted in it the scraper-blade 21, said b ade being supported at its ends by arms 22 which are exterior roller 12, and it may from all the er contacting to the ends of the receptacle 20 and secured thereto in a pivotal manner by rivets or the like 23. The bladell will be moved to a substantiall vertical position when its ed e is to be placed in engagement witht e e secured in such position by hooks 24 secured to the arms 22 and pins 25 projecting from the ends of the receptacle 20. en it is not desired to use the blade 21, as during the ordinary o eration of the press, the blade ma be a lowed to recline against the side 0 the receptacle, as indicated by dotted lines in 'lhe composition on the roller 12 may vary in character but will be a yielding composition which, like the other composition rollersmf the ress,is im ervious to kerosene and like so vents of i' and I utilize this roller, in connection with the scraper 21, to clean all of the rollers and preferably the form cylinder without the use of water.

When it is desired to clean the rollers, the'roller 16 will be placed out of operation so that it will not transfer ink from the font 11 to the adjacent roller 15, and thereu n the press being continued in motion, t e attendant will a ply kerosene to almost any of the series of rollers but referably to the roller 12 and to a more limltedextent to the roller 18 and; its adjacent roller 14 and then after-a moments delay to enable the kerosene to cut up the ink, the s'cra er 21 will be turned upwardly to its vertical position shownin Figs. 1 and 8 and secured y hooks '24 or other suitable means. The kerosene will be transferred from one to the other of thelrollers in series and act as a solvent to the ink thereon, and the scraper 21-will remove the ink and solventfrom the roller 12 and thereby create at said roller and at the point where it is cnga by the scraper a source of discharge for t e ink and solvent from all the rollers and form 10 as well, since the ink and solvent'seekin a uniform distribution on all the contactingsurfaces willconstantly mo've to an gley the roller 12, which is as constantly rel d by the scraper 21 of the suplply 'ven to it, the result bein that the to er 1 will draw surfaces and the scraps! will be enabled to remove all the ink and solvent. from all the rollers and the form. Since all of the rollers and the form are in contact with one another one scraper blade will effectually clean all the rollers and form by the transfer process above described.

In the employment of my invention 1 p'efer to use kerosene as the main solvent the ink, and near the conclusion of the cleanin operation I preferabl apply to the To lers or form or both a limited quantity of benzene as a finish to the operation. The uantity of solvent employed will depend on t e'character of the ink used on the press, an ink of strong quality requiring more solvent than a very soft or a very cheap ink, such, for example, as is used or printing news ijipers on modern presses, and 'there may e some thin inks used which would not require the emplo ment of any or at most only a very sma quantity of solvent during the cleaning operation.

My invention does not add materially to the cost of the press, and it enables the rapid automatic cleaning of the rollers.

The efliciency of my invention resides in applying the scraper 21 to a composition or a composition surfaced roller, and while I greatly prefer to apply the scraper to a main istributer roller 12, I do not desire to limit my invention to such location of the craper because obviously this scraper can applied to an other com osition or comosition surf roller in t e train of rollers. Itis' essential, however, that the sore er be applied to a composition or composition surfaced roller and. not to one of the iron rollers.

cause of its great fliciency in attacking The ink-distributing mechanism shown is y a c linder-distributin feed and while enera ly speaking a cylinder-distributing mkfeed is not new, I 'ow of no instance'in which the main distributer roller or c linder 12 has been a composition roller either in a cylinder press or a flat form press.

What I claim as my invention and desire to secure by Letters Patent, is:-

1. In combination with a printing press having a form cylinder, form rollers, and ink distributin rollers in a train, a scraper rollers while they are on the press, said scraper blade being a plied to a compositionroller connected in th train so as to remove the ink and solvent therefrom and thus cause a transfer of the ink and applied solventthrough the train to said roller, whence they are removed; substantially as set forth.

2. In combination with a printing press havin a form'cylinder, form/rollers, an nk distributing rollers, the main distributmg roller being of composition a scraper blade applied to said main istributmg rollerfor cleaning ink from all the rollers by a erprocess, and a receptacle to re- 115 blade for efl'ec ing the cleaning of all said i ceive the matter removed by the blade; snbmeans for locking the scraper in its operastantially as set forth. tive position; substantially as set forth.
